And the book on all three is already being written.

Here is a closer look at the Penn State players …

ALLEN ROBINSON

Robinson, who caught 174 passes for more than 2,400 yards and 17 touchdowns the last two seasons at Penn State, is praised for his size (6-3, 210) and his ability to get away from press coverage. In addition, Robinson's superb playmaking skills on jump balls is another strength, as his run-after-the catch ability.

NFL.com also notes that Robinson does not have blazing speed and that he can improve as a blocker.

"Robinson is a big, fluid, outside receiver with a nice combination of 'above-the-rim' prowess and run-after-catch ability,'' according to NFL.com. "(He) offers possession skills, playmaking ability and red-zone utility to develop into a solid No. 2 option.'''

Robinson's NFL.com grade: 5.7

DAQUAN JONES

Jones enjoyed a breakout 2013 season and was named first-team All-Big Ten after registering 11.5 tackles for loss.

The 6-3, 323-pounder has the size and strength to hold up inside, NFL.com notes, and he also earns praise for his quick first step. Jones receives high marks for his ability to collapse the pocket and his athleticism to play in more than one scheme.

NFL.com's report points out that Jones has taken plays off on occasion and he isn't much of a pass-rush threat. The report also raises questions about his weight and conditioning.

"Big, strong-bodied interior force who shed weight and improved his stamina as a senior, displaying NFL-caliber physicality in the trenches,'' according to the NFL.com evaluation of Jones.

"(He) has been inconsistent in the past, but if the light has come on, Jones’ combination of size, power and movement enables him to play as a 4-3 one-technique or 3-4 five-technique.''

Jones' NFL.com grade: 5.65

JOHN URSCHEL

The 6-3, 317-pound Urschel is well-known as one of college football's top student-athletes, having earned a 4.0 GPA in math. Urschel is also a two-time first-team All-Big Ten choice.

Naturally, the NFL.com evaluation singles out Urschel's intelligence and the lineman also earns high marks for his balance, body control and his ability to gain leverage. Other strengths for Urschel are his footwork and his familiarity with a pro-style offense.

As for Urschel's perceived negatives, NFL.com notes he is actually a bit undersized for a guard and that he "plays short-armed". He is not considered explosive or powerful.

In conclusion, the evaluation speculates that Urschel might be better suited for another position on the offensive line.

"Underpowered, quick-footed, scrappy, zone blocker with the smarts, movement skill and competitive zeal to emerge as a very efficient pro,'' according to NFL.com.

"Displays the quickness highly desired at the pivot and might prove to be best at center.''
